QString remove from the end untill a specific character

Sucharek

Hi, I'm trying to find a simple way to do this. I already made something that works, but it's a mess and I think there's a simpler way to do this.

Here's what I did:

QString test = "Android/media/com.whatsapp";
std::reverse(test.begin(), test.end());
QString ola = test.mid(0, test.indexOf("/"));
std::reverse(ola.begin(), ola.end());
int ren = ola.count();
test.remove(0, ren);
std::reverse(test.begin(), test.end());
qDebug() << test; //prints "Android/media/"

Is there an easier way to do this?

test = test.left(test.lastIndexOf('/') + 1);

or

test.truncate(test.lastIndexOf('/') + 1);

or

test = test.section('/', 0, -2, QString::SectionIncludeTrailingSep);

see QString::lastIndexOf()

QString test = "Android/media/com.whatsapp";
int position = test.lastIndexOf( QDir::separator() );
if ( -1 != position ) {
    test.remove( 0, position + 1 );
}

test = test.left(test.lastIndexOf('/') + 1);

or

test.truncate(test.lastIndexOf('/') + 1);

or

test = test.section('/', 0, -2, QString::SectionIncludeTrailingSep);

Hi @Chris-Kawa, your solution is probably the shortest and simplest.
I'll use one of these 3 commands. Thanks

Thank you for replies from others.
